Model-Comparison-for-Cisco-Catalyst-3650-Series-Switches.jpg

StackWise-160 Technology

The Cisco Catalyst 3650 provides maximum data, power, and wireless resiliency using Cisco StackWise-160 technology, which is built on the highly successful industryleading CiscoStackWise technology. The StackWise-160 technology provides optional stacking with 160 Gbps of bandwidth for providing resiliency within the stack. The stack behaves as a single switching unit that is managed by an active switch elected from one of the member switches. The active switch creates and updates all the switching, routing, and wireless tables. In an event of the active member failure, the standby member assumes the role of the active switch, continuing to keep the stack operational.

 

Cisco Catalyst 3650 Primary Advantages

Converged Wired and Wireless Platform

The Cisco Catalyst 3650 is a stackable platform that converges wired and wireless services on a Cisco IOS XE Software based platform. The CAPWAP tunnels from the access points terminate at the 3650 switch, enabling users to configure and apply software features such as QoS, security, and FnF across wired ports and wireless SSIDs on the same switch at the same time. The converged wired and wireless platform supports the Cisco Unified Access solution. With “one policy, one management, one network,” the Cisco Catalyst 3650 and Cisco Unified Access help IT spend less time running the network and more time on business innovation.

Advanced Security

The Cisco Catalyst 3650 is hardware capable of supporting Cisco TrustSec functionality. Cisco TrustSec uses the device and user credentials acquired during authentication for classifying the packets by security groups as they enter the network with scalability and simplified management. The classification is maintained through the network by the security group tag (SGT) and through integration with the Cisco Identity Services Engine. The Cisco Catalyst 3650 is also hardware-ready for link layer MACsec encryption, which provides networkwide encryption to protect data traffic across the network.

Application Visibility and Control (AVC)

With the native support for FnF on all the ports, the Cisco Catalyst 3650 can monitor both east-west and north-south wired traffic at the same time. The Cisco Catalyst 3650 switch terminates the wireless CAPWAP tunnels from the access point, providing full visibility into the wireless traffic at the switch. Because the wireless traffic is now isible at the switch, it is possible to identify wireless traffic using FnF and prioritize the traffic using advanced QoS capabilities for an improved user experience and faster troubleshooting.

SmartOperations

The Cisco Catalyst 3650 supports Cisco Catalyst SmartOperations. SmartOperations features such as Auto Smartports, Auto QoS, and Smart Install reduce deployment time by automating most of the basic switch and port configurations.

Foundation for Cisco ONE Enterprise Networks Architecture

The Cisco Catalyst 3650 is built on the UADP ASIC, which provides wire-rate hardware performance with software programmability. The UADP ASIC features a programmable data plane, enabling deployment of SDN services and support of future software features over the product lifetime. The Cisco Catalyst 3650 supports the Cisco ONE Enterprise Networks Architecture for openness, programmability, and operational simplicity.

Reduced Total Cost of Ownership

The Cisco Catalyst 3650 reduces the total cost of ownership and provides superior investment protection through:

Built-in wireless controller functionality

Optional stacking

Support for fixed GE or 10 GE uplink

Support for IP Base and IP Services software options

Dual redundant power supply and three individual fans to help ensure high availability

E-LLW with NBD advance hardware replacement and 90-day access to Cisco TAC support

Cisco Nexus 3100: Next-gen Merchant Silicon-based ToR Switch Series

October 22 2013 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

Cisco expanded its line of merchant silicon-based, top-of-rack data center switches with its new Nexus 3100 series.nexus-3100.png

Like other switches in this family, including the Nexus 3000 and 3500 series, the Nexus 3100 is a low-latency, high-density Layer 2 and Layer 3 switch. And because it is based on merchant silicon, the Nexus 3100 series does not support FabricPath, Cisco's TRILL-based Layer 2 mulit-pathing technology, or Cisco's fabric extender technology. In other words, like previous Nexus 3000 switches, the Nexus 3100 is not a part of Cisco's FabricPath-based data center fabric strategy.

Instead, Cisco is positioning the Nexus 3100 as a top-of-rack device for enterprises that require high-density, low-latency, top-of-rack switches that can be deployed in a leaf-spine architecture using conventional Layer 3 protocols.

Cisco also said the Nexus 3100 will support a variety of software-defined networking (SDN) capabilities, including its onePK SDN interface, virtual extensible LAN and OpenFlow 1.0. Cisco did not specify if or when it will start supporting the newer OpenFlow 1.3 specification.

Cisco didn't announce when the new switch will start shipping, but promised more details would be available "in the coming weeks."

The Nexus 3100 comes in two flavors. The Nexus 3132Q is a 2.56 Tbps switch that ships with 32 ports of 40 Gigabit Ethernet (GbE). The Nexus 3172PQ is a 1.44 Tbps switch with 48 10 GbE ports and 6 40 Gbps ports. Cisco claimed these switches will support Layer 3 in-service software upgrades. Although it claimed the switches will be ultra-low latency, Cisco has not published exactly how low that latency will be.

Cisco Nexus 3132Q vs. Cisco Nexus 3172PQ

Cisco Nexus 3132Q vs. Cisco Nexus 3172PQ

Cisco envisions two use cases for the Nexus 3100 series, according to Jimmy Shah, product manager at Cisco. First, the switches can serve as server access switches, particularly as leaf switches in a leaf-spine data center network. Second, the Nexus 3132Q, with its high-density 40 GbE ports, can serve as a pizza-box spine switch in the same leaf-spine environment.

Cisco's Nexus 3000 switches were seen by many experts as a response to rival Arista Networks' success in selling merchant silicon-based, ultra-low latency switches into financial trading firms. Cisco is calling the Nexus 3100 line the second generation of those switches.

"This is a big step up from the Nexus 3064," Shah said. "We see a lot of our 3064 customers transitioning to this product. If I'm building a new data center and I'm looking for the densest 10 Gb switch, then the 3100 becomes a great choice based on these hardware and software features."

Cisco Refreshes Campus Switching, Including Catalyst 6800 Core Chassis

July 3 2013 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

Cisco unveiled a refresh of its campus switching and enterprise routing products at Cisco Live this week, highlighted by the Catalyst 6800 series, a big brother to the Catalyst 6500 that is compatible with the older switch's existing supervisor modules and line cards.

Cisco-catalyst-6800-series.jpg

The new Catalyst 6807 is a 10/40/100 Gigabit Ethernet (GbE) modular switch with 11.4 Tbps of total throughput and 880 Gbps capacity per slot. It has five times the performance and six times the capacity of the venerable Catalyst 6500. Because it is compatible with the modules designed for the Catalyst 6500, this new switch hits the market with all the advanced services that customers usually have to wait a couple years for, such as the Wireless Services Module and Multiprotocol Label Switchingsupport.

"The Catalyst 6500 has an 80 Gb-per-slot limit, so they just couldn't work around that," said Andre Kindness, senior analyst with Cambridge, Mass.-based Forrester Research Inc. "So they came out with the 6800. The chassis had to change to accommodate 100 Gb throughput."

Kindness said the Catalyst 6800's compatibility with modules from the 6500 offers customers a new level of investment protection.

"This is the first time I've seen a vendor come out with a new chassis and be able to create a switch with higher speeds without having to build new modules," he said.

Switch to run on upgraded Supervisor Engine

The Catalyst 6807 will run on the Supervisor Engine 2T (Sup 2T) module, which was introduced as the next-generation supervisor for the Catalyst 6500 two years ago, said Inbar Lasser-Raab, Cisco's senior director of enterprise network marketing. Cisco has upgraded the software on the Sup 2T for the new chassis.

Paris-based utility giant EDF plans to adopt the Catalyst 6807 in a large network refresh. "We have a big project to replace all of the networks in our nuclear power plants, hydro-power plants and thermal power plants. We chose to place the Catalyst 6800 at the heart of this network," said Dominique Massoni, senior ICT architect for the global core at EDF.

Don Prince, senior IT architect with Atlanta-based Southern Company, said he appreciated "being able [to] use the same services and take advantage of the same line cards and other equipment [from the Catalyst 6500] that is compatible with the 6800. Investment protection is important to us."

Additionally, Cisco introduced a semi-fixed form factor model Catalyst 6880, a 10 GbE switch designed for midmarket customers who want a switch with moderate 10 GbE density and some advanced services. The Catalyst 6880 is a 4 rack-unit switch with 16x10 GbE fixed ports and half slots that can service an additional 80x10 GbE ports.

Wiring closet device optimized for campus

Cisco also announced a wiring closet device, the Catalyst 6800ia (Instant Access), a 1 rack-unit device with 48 GbE ports that extends the services and the image of a Catalyst 6500 or Catalyst 6800 to the access layer of a network.

"It's analogous to a [Nexus 2000 fabric extender], except that it's optimized for the campus, with features like PoE [Power over Ethernet]," said Rob Soderbery, senior vice president of Cisco's enterprise networking group.

Unlike the Nexus 2000, which extends the ports of a Nexus 5000 or 7000 data center switch to the top of a rack, the Catalyst 6800ia virtually adds ports to the core Catalyst devices. These additional ports are physically located in wiring closets on the 6800ia, but they exist logically on the chassis switch.

"I got immediately excited about the [Catalyst 6800ia] because my company could triple in size and I wouldn't have to increase the size of my networking staff," said Chris Tillett, network administrator with Halifax Media Group, a Daytona Beach, Fla.-based publisher that owns more than 30 newspapers. Since the Catalyst 6800ia extends the image of an existing core switch, a network engineer doesn't need to deploy and configure it. Tillett said he can send the device to an IT generalist who can simply plug it in and the device is up and running.

Cisco enhanced another part of its campus portfolio by introducing a new supervisor module for the Catalyst 4500. This new module features Cisco's Unified Access Data Plane (UADP) application-specific integrated chip (ASIC), which allows customers to integrate wireless LAN control into their switching fabric. Cisco first introduced this ASIC on its Catalyst 3850 stackable switch.

Finally, Cisco beefed up its enterprise routing products with a new top-of-the-line Integrated Services Router (ISR) 4451-AX [Application Experience]. This router ships with 1 Gbps performance, but its software license can be upgraded to 2 Gbps. All Application Experience features introduced recently on other ISR models ship on this new 4451-AX, but all the services are integrated directly into the box. No additional modules need to be installed. All advanced services, including Wide Area Application Services (WAAS) and security, operate at line rate.

Forrester's Kindness said existing ISR models provide all the Layer 4-7 services that the new ISR 4451-AX offers, but this new model has much better performance. Earlier models delivered those services as if a customer "was deploying a server on top. They can't do WAAS at full performance. This router is integrating Layer 2 through 7 so you can do WAAS and security at 1 to 2 Gb line speed."

Cisco also rolled out the Application Experience services package to the ASR-1000 router, which can be added to existing deployments through a software upgrade. Cisco said the 6807 and 6880 switches will be available in November. Other products and upgrades will be available in July.
